ABRAM TILTON, OF BROOKLYN, AND AUGUST HORMEL, OF NElV YORK, N. Y.

MACHINE FOR DECORATING WOOD.

SPECIFICATION forming part of Letters Patent No. 482,855, dated September 20, 1892.

Application filed October 29, 1891.

To all whom it may concern.-

Be it known that we, ABRAM TILTON, of Brooklyn, county of Kings, and AUGUST HOR- MEL, of the city, county, and State of New York, citizens of the United States, have invented certain new and useful Improvements in Machines for Decorating Wood, of which the following is aspecification.

Our invention has reference to improvements in machines for ornamenting wood and other surfaces by pressure; and the objects of our improvements are, first, to provide the machine with a standard and roller-bearings which are divided in halves that can be swung apart for the purpose to change the rollers; second, to afford facilities for simultaneously rotating the pattern and feed rollers, and, third, to provideaspecial lever mechanism for producing a spring action on the feed-roller.

In the accompanying drawings, Figure 1 is a front view of ourimproved machine for ornamenting wood and other surfaces. Fig. 2 is a vertical section on line a: :0, Fig. 1; and Figs. 3 and 4 are respectively a front and a back view of the machine.

Similar letters of reference indicate corresponding parts.

A and A are the end standards, and A is the middle standard, of the machine, which are connected with each other at their upper ends by a cross-bar and angle-pieces A The standards A and A have fixed bearings B and B and adjustable bearings C and O, the latter capable of sliding in guide-grooves in the said standards, as indicated in Figs. 2 and 4. A roller D is fitted with its shaft in the fixed bearings B B and a roller D fitted in tche same manner in the adjustable bearings The standard A consists of halves a a,

j which are secured to one of the angle-pieces of the cross-bar A by means of screws a and hinged by pivot-pins a to the bottom pieces a of the said standard. The bearings Band Ca-re likewise divided in halves, as shown in Fig. 4. The standard A, together with the bearings B and O, can thus be opened for the purpose to change the rollers for new patterns. The adjustable bearings O and Orest on screw-rods d d, having screw-nuts e 6,

which latter are supported by hubs ff, fastened to the transverse rail E.

The rail E is provided at its ends with anglepieces 9 g, which are guided in grooves in the standards A and A. The rail E carries brackets F F, in which the shaft g is loosely fitted,to which shaft beveled gear-wheels hh are keyed, that mesh with the toothed conical wheel outside of the screw-nuts e e. A third bracket 77, is attached to the transverse rail E, in which a revoluble shaft 10, having a hand-wheel K, is fitted. The shaft is has a beveled gear-wheel i meshing with a beveled gear-wheel i, bolted to the shaft k. By turning the hand-wheel K to the right or left hand side the shaft g is simultaneously turned and the gear-wheels h and h at the ends of the said shaft engage the screw-nuts e e, the outer conical surfaces of which are toothed, as aforesaid. The screw-nuts lower or raise the screw-rods, as the inside threads of the nuts engage the threads of the rods. The adjustable bearings O O of the lower roller D are thus raised or lowered by turning 7 5 the hand-wheels K either to the right or left hand side.

To the rail E two lever-armsll are hinged, which are fulcrumed to the supports m m, standing on the floor. The said lever-arms Z Z are connected with each other by a connecting-rod n, to which they are pivoted. A lever 0, which is provided on its free end With a weight 0, is fulcrumed by means of a pin n to the connecting-rod n, and hinged to a support 0 also standing on the floor. The weight on the free end of the lever 0 causes to hold the rail E and the adjustable bearings O O, with the roller D, in the proper position and produces a spring action on the latter, so as to allow it to yield in case too much stress is exerted on the same. The adjustable bearings O C have inwardly-extending brackets L L, carrying the table L attached to the same on a level with the top'of the roller D. 5 The feed-table which serves to guide the wood or other material to be ornamented between the rollers is not shown in Figs. 2, 3, and 4.

To the shafts of the rollers D and D gearwheels M and M are keyed, which are located ico between the standards A and A the shafts being fitted in the fixed bearings 13 and B and the adjustable bearings C and C of the standards A and A respectively. The gearwheel M meshes with a pinion N, Fig. 2, on the shaft 19, which shaft is fitted in a bearing 5 suitably attached to the standards A and A (the bearings being not shown in the drawings) and in a bracket-arm O, screwed or otherwise attached to the standard A A loose pulley P, having a pinion p firmly attached thereto, runs on the shaft 19, which pinion meshes with a gear-wheel R, keyed to the shaft r, that turns in the bracket-arm O and the standard A.

To the shaft r a pinion R iskeyed, whit-"h engages the gear-wheel P, that is firmly attached to the shaft p.

By the power transmitted to the loose pulley P and the pinion p rotary motion is transmitted to the gear-wheel R and the pinion R, and from there to the gear-wheel P and to thepinion N.

At both sides of the pinion N links S S are loosely fastened to the shaft p,which links are hinged to two other links T T, which latter are loosely attached to the shaft of the roller D at both sides of the gcar wheel M.

On the shaft by which the links S S and T T are connected with each other turns a gear-wheel M that meshes with the pinion N 0 and the gear-wheel M. The rotary motion of the pinion N is thus transmitted to the gear-wheel M of the roller D,which is generally provided with the engraved pattern, and through the gear-wheel M to the gear-wheel 3 5 M of the feed-roller D, so that to both rollers rotary motion is simultaneously imparted. This always will be the case no matter whether the roller D and the feed-table are lowered or raised by the hand-wheel K and the lowering or raising motion of the screw-rods d d imparted to the same by turning the handwheel to the right or left hand side, as before described.

The gear-wheels M and M of the rollers are not shown in Fig. 3.

Our machine for ornamenting wood and other surfaces is far superior to any other machine of this kind, as our mechanism by which the feed-roller and the feed-table are raised or lowered is very simple and the ro- 5o tary motion of the rollers is rendered entirely simultaneous and equal.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a machine for ornamenting wood and other surfaces, the combination of a standard divided in halves, which are pivoted to the base of the standard, with roller-bearings also divided in haves and attached to the respect- 6o ive halves of the standard, and an angle-piece of the upper cross bar of the machine, by which angle-piece the halvesof the standard and of the roller-bearings are held together, substantially as set forth.

2. In a machine for ornamcnting wood and other surfaces, the combination of the ad justable rail E,havingon its ends supporting-rods for the adjustable bearings of the feed-roller, with the lever-arms Z l, the connecting-rod n, connecting the said lever arms with each other, and the weighted lever o, fulcrurned to the connecting-rod, substantially as set forth.

3. In a machine for ornamenting wood and other surfaces, the combination of pulley P, having pinion p on shaft 19, with gear-wheel R and pinion R onshaft r', gear-wheel P and pinion N on shaft 19, gearwheel M links S S, attached to shaft 19 and the shaft of said gearwheel, links T T, attached to shaft of feedmill D and the shaft of gear-wheel M and gear-wheels M and M of the rollers D and D, respectively, substantially as and for the purpose set forth.

Signed at New York this 21st day of September, 1891,in the presence of two witnesses.
